Lamprobityle katrinae sp. nov.

( Fig. 2 )

Type material. Holotype. Female : Philippines: Samar Isl., Hinabangan, 08.2014, local collector leg. ( DUBC).

Description. Body length 8.7 mm, width 3.5 mm. Body black; surface roughly dotted and in some places covered with fine tomentum. Legs and antennae red.

Head small, black and with slightly metallic gloss. Clypeus brown, glossy. Labrum black, with metallic gloss. Head covered with fine grey tomentum and outstanding setae; ventral surface smooth and shiny. Eyes large, double-lobed; they surround elevated antennal bases from one side. Forehead between antennal bases sunken, with narrow longitudinal corrugation. Antennae relatively long and thin, not reaching apex of elytra at females. Antennal segments covered with fine tomentum and longer setae. Basal antennomere red. Second antennomere black, with blue metallic gloss. Third antennomere red, darker basally and apically, with metallic gloss, dentiformly enlarged and thicker at apex. Residual antennomeres dark, covered with silver-grey tomentum, slightly darker at their apices.

Lamprobityle katrinae sp. nov.

Pronotum cylindrical, slightly wider than long, completely marginated in posterior border, with transversal furrow. Surface of pronotum strongly and sparsely puncturated, with fine and sparse tomentum. Scutellum black, round at apex, with pale tomentum in medial part.

Elytra long, not parallel sided; elytra between humeri and middle part slightly narrowed and widened posteriorly, widely rounded in their apical part. Elytra roughly dotted, broadly impressed between humeri and medial parts of each elytron, with convex protuberances behind humeri. One fourth of base black, with very fine sparse tomentum. Other one fourth of base covered with dense silver grey tomentum, and looks like greyish wide transverse stripe. Residual part of elytra black with fine sparse tomentum.

Legs red. Mesa- and metafemori black, with bluish luster. Tarsi black, with blue gloss. Tarsomeres flattened, covered with short tomentum and long setae.

Ventral side of body roughly dotted, covered with silver-grey tomentum.

Differential diagnosis. This species differs from all other currently known congeneric taxa by the shape and coloration of elytra, legs and antennae. It is slightly similar to L. (s. str.) azurea (Vives) from Samar Island, but L. katrinae sp. nov. has smaller body size, other coloration of antennes, legs and dorsal surface of the body.

Distribution. Philippines: Samar Isl. This species is probably endemic to Samar Island.

Etymology. The species is named in honour of my daughter Katrīna Barševska, in gratitude for co-operation in research on Latvian beetles.
